Dummy content, also known as placeholder text, is used in the design and development stages to fill spaces where actual content will be inserted later. It helps designers visualize how text or data will appear on a web page or document. Commonly, “Lorem Ipsum” is used as dummy text for readability and layout purposes. Dummy content ensures that visual elements like fonts, spacing, and alignment can be tested. It is temporary and typically replaced with real content before the final product is published.
